背斜

It is possible that domes or long walls may be created independently in the horizontal strata. Thus, synclines and anticline develop in different extent and may be distributed in space with different directions. Nevertheless, some of them may be arrangeddirectionally.

穹窿或长垣可以弧零零的产出于水平岩层之中，所以向斜和背斜不同等发育，而且空间展布常无一定方向性；有些穹窿或长垣也可稍呈有规律的定向排列。

These develop from the gentle flexural undulations of earlier stages, which start to be visibly amplified by 3km shortening, and form quite strong peripheral anticlines and synclines by 8km shortening, decaying away from the fault.

这些褶皱是从早期轻微的挠曲起伏演化而来的，到挤压位移3km时，它们开始明显增强，到挤压位移8km时，已经形成非常大的背斜和向斜，其幅度从断层向两侧逐渐减小。

Among such features may be synclines and anticlines, geological faults , salt domes, undulations of the crystalline bedrock under a cover of moraine, ore bodies, clay deposits and so on.

例如向斜、背斜、断层、盐丘，冰碛层之下结晶岩的顶面起伏形态，矿体以及粘土矿床等。

Connecting sand body migration systems may controls the forming of oil-gas reservoir due to bottom bed overlap. lithologic pinch out, and/or the fault barrier. The migration system consisting of unconfornfity surface, sand bodyunconformity surface, and/or unconformity surface-fault, may control the forming of the bedrock weathered crust type oil-gas reservoir. The migration system consists of fault, sand body-fault, and/or sand body-unconformity surface, may control formation of oil-gas reservoir due to fault block, anticline, structure-lithologic, and/or fault-lithology.

连通砂体输导系统可控制底层超覆、岩性尖灭、断层遮挡油气藏的形成；不整合面、砂体-不整合面、不整合面-断层组成的输导系统可控制基岩风化壳油气藏的形成；断层、砂体-断层、砂体-不整合面-断层组成的输导系统可控制断块、背斜、构造-岩性和断层-岩性油气藏的形成。

The strike of Huanghai block and Huaihai block in the east mainly tends towards north-east, while the strike of Shanxi block and the eastern edge of Ordos block in the west mainly tends towards north-west.(3) According to the feature of Moho, the crust of the research zone can be divided into six parts in the Shanxi block, Moho looks like a nearly north-south sunk belt, and the crust is thick; at the southern edge of the Inner Mongolia block and in the south of Yanshan block, Moho presents the structural features of fold belt, tending nearly towards east-west; at the eastern edge of Ordos block, the structure of Moho is relatively complex with nearly northwest folds.

3根据莫霍面的形态特征，研究区地壳可大致划分为6个区块；在山西地块范围内，莫霍面呈近南北向的凹陷带，地壳厚度大；内蒙古地块南缘和燕山地块南部，莫霍面表现出褶皱带的构造特征，其延展趋势为近东西方向；鄂尔多斯地块东缘，莫霍面构造相对复杂，呈近北西向凸、凹相伴的褶皱；黄淮海地块为莫霍面隆坳区，隆、坳相间排列，构造较复杂，但从整体上看，这是全区莫霍面最浅的隆起区段；鲁西台背斜主要为莫霍面断陷区，其断陷带沿枣庄－曲阜一线向北西方向延伸。

The Sheep Mountain anticline in Bighorn Basin, Wyoming, is part of the Rocky Mountains.

绵羊山背斜落矶山羊盆地，怀俄明州，是落基山脉的一部分。

With reference to the reservoir conditions, the oil and gas can be trapped not only in the anticline and fault block of the reservoir, but also in the lithologies that can form a great scale of oil and gas field. The study of the lithological oil and gas reservoir enables the seismic lithological theory and especially the AVO technique to take great progress

石油、天然气的储集条件说明：油气不仅能保存在储集层背斜、断块等一类正向圈闭中，也能在具备有储集条件的岩性体中聚集起来，并成为相当规模的油气田，对岩性油气藏的研究，使得地震岩性学特别是AVO技术得到了发展。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
